UNITED STATES MILO GAGE, OF MEDINA, NEW YORK.

STOVE-PIPE DRUM.

Specification forming part of Letters Patent No. 53,806, dated April 10,1866.

To all whom it may concern:

Be it known that I, MILO GAGE, of Medina, in the county of Orleans andState of New York,have invented a new and useful Improvement inHeat-Radiators for Stove-Pipes and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, making part .of this specification.

Figure l is a perspective view of my improved heat-radiator; Fig. 2, acentral vertical section of the same; Fig. 3, a diagram exhibiting asection of the pipes, and showing more particularly the method ofproducing the indirect draft.

Like letters of referenceindicate corresponding parts in all thefigures.

My improved radiator belongs to that class that are employed between thejoints of stovepipes.

The invention consists in the combination of a main and auxiliary tubes,with chambers at the top and bottom, so arranged that, while a greatradiating-surface and a direct draft are produced, an indirect draft mayalso be produced byturning said draft downward through every alternateauxiliarytube and upward again through every intermediate one, when itis finally allowed to escape.

As represented in the drawings, A is the main central tube, B B B B theauxiliary tubes surrounding it, and G D the chambers at the top andbottom, which are provided with the usual flanges a a to connect withthe joints of pipe. The lower chamber, 0, simply incloses an annularspace with the central tube passing through it and the auxiliarytubes opening into it from the top. The upper chamber, D,isdividedintotwo compartments, gh, by a horizontal partition, I), having a damper orvalve, 0. The upper compartment communicates through to the main pipebeyond, to allow the passage of the draft after it has finally passedthrough the tubes, as will presently be explained.

Every alternate auxiliary tube B simply opens through the floor f intothe lower com partment, g, of the upper chamber, while everyintermediate tube B passes through the lower compartment and thepartition I), and opens into the upper compartment, h. This arrangementis clearly exhibited in Figs. 1 and 3.

In kindling a fire, and whenever a direct draft is necessary, the damperc is opened, as

indicated by red lines in Fig. 2, thus leaving the passage-way throughthe large central tube unobstructed. When the damper is closed, as inblack lines, the draft collects in the lower compartment, g, and therebeing no escape except through the tubes B B, it passes downward intothe bottom chamber, (1, and thence passes up again through the tubes B Binto the upper compartment of the chamber D and escapes.

The employment of the tubes A B B exposes a greater surface forradiation than any other arrangement with which I am acquainted. Soobvious are its advantages in this respect that a device has alreadybeen patented involving the same idea; but in such device the draft isdirect through the auxiliary as well as the main tubes. Incontradistinction to this, the essential feature in my device consistsin givingareturn orindirectdraftthrough the auxiliary tubes, so as toretain the heat as long as possible. To secure this resultIcombine withthe tubes the chambers O D, which not only have the special effect ofsecuring the indirect draft, but also serve as radiatingdrums forthrowing out much additional heat.

This combination of the chambers with the tubes, wherebya direct orindirect downward draft may be produced, and at the same time themaximum amount of radiating-surface be secured, I believe was neverbefore known.

I do not claim simply an arrangement of auxiliary tubes when the draftis direct, nor do I claim, simply and broadly, producing a return orindirect draft; but

Whatlclaim as myinvention, and desire to secure by Letters Patent, is

The combination of the chambers G D with the tubes A B B, the chamber Dbeing divided into the two compartments 9 h by the partition b anddamper c, and the tubes B B connecting alternately with saidcompartments, the whole operating in such a manner as to combine theadvantages of a direct and indirect draft with a large amount ofradiating-surface, substantially as herein specified.

MILO GAGE.
